Abstract
A methanation reactor, to be used preferably in an integrated urea-ammonia process for methanizing carbon oxides is disclosed, in which the catalyst bed and an underlying heat exchanger of the tube-bundle type make up a unit mounted centrally of the reactor casing with a gap left between the reactor casing inside wall and said centrally mounted unit. Fresh gases to be methanized enter the gap, then the heat exchanger from below and flow upwards to the catalyst bed, whereafter they flow down to the exchanger again. Incoming gases sweep the exchanger tubes from the outside, while the reacted gases flow in the interior of the tubes of the heat exchanging bundle. Insulation blankets and gland seals are provided.
